Abstract

L'invention porte sur un dispositif de commande de grappes de contrôle (CRDM), lequel mécanisme est configuré de façon à se verrouiller sur la barre en élévation d'un assemblage de commande, et lequel comprend des mécanismes de prise de verrou et de maintien de verrou séparés. Un CRDM est configuré de façon à se verrouiller sur la barre de levage d'un assemblage de commande, et comprend une liaison à quatre barres fermant le verrou, la liaison à quatre barres sollicitant le verrou vers la fermeture sous l'effet de la force de la gravitation.
